PHILIP ZALKIN'D, OF NEW YORK, N. Y.

CONTAINER.

Application filed m 30, 1921. Serial in. 488,574.

To all whom it may concern:

Be it known that I, PHILIP ZALKIND, a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented an Improvement in Containers, of which the following is a specification.

This invention relates to a container and more particularly to that form of container usually made of cardboard or similar material and adapted in use to receive and hold the container inorder to prevent the. contents thereof from sifting through the same. The object of the present invention is to provide a container having the ends thereof closed in such a manner as to cause the same to be substantially sift-proof and thus make it possible to dispense entirely with the use of the liner or the envelop for preventing the contents of the container from sifting through, and to, prevent extraneous matter from entering the container.

To this .end in carrying out the invention the container made in accordance therewith is preferably constructed of cardboard or similar material and so formed as to have the ordinary sides or walls of the container makinguthe same of any preferred shape, while the ends of the container, together with the usual flaps or end panels include inturned set in panels adapted to reinforce the ends of the container andv to coact with the end flaps or panels inclosing the ends of the container in such a manner as to make the same substantially sift-proof.

The invention will be hereinafter more particularly described in conjunction with the accompanying drawings in which,

Referring to the drawing and particularly to Figs. 1 to 5 inclusive, it w1ll be seen that one form of the container madein accordance with my present invention is formed from a blank as illustrated in Fig. 1. This blank is scored or creased along predetermined lines and cut or severed along predetermined other lines to provide the sides or walls and the end flaps or panels to make the container. The walls or sides'of the container are indicated at 15, 16, 17, and 18.. The end panels or flaps for oneend of the container are indicated at 19, 20, 21 and 22, while the similar parts at the other and i the container are mdmute at 23, 24, 25 and 26. The wall 15 is provided with a flap or an extension 27 adapted in the usual manner to be secured to the wall 18 along the dotted line 28 to form the container, the flap being secured to the wall by a suitable adhesive or in any other suitable manner. The end panels 19 and 22 inclusive are scored or creased along the line 29 which is parallel to and suitably spaced from the line 30 defining the portion between the walls 15 to 18 inclusive and their respective end flaps or panels 19 to 22. Similarly the end panels 23 to 26 inclusive are scored or creased along a line 32 whichis parallel to and suitably spaced from the score line 31 defining the walls 15 to 18 inclusive at their other ends and thefr respective-end flaps or panels 23 to 26.. There is thus formed'a series of panels or plaits adapted to be inturned and secured to the upper surfaces of the walls of the container. The inturned panel or. plait between the wall 15 and its flap 19 is indicated at 33, that between the wall 16 and its end flap 20 by 34, that between the wall 17 and its end flap by 35 and that between the wall 18 and its end flap 22 by 36. Similarly the inturned panels or plaits at the opposite end of the container are indicated at 37, 38, 39 and 40.

In this form of the invention the blank, after being cut and scored as indicated in Fig. 1, is first folded along the line 30' and then along the line 31 so as to cause the parts to assume the position shown in Fig. 3. In

folding the parts to this position the adjacent surfaces of the inturned .panels or plaits 33 to 36 and 37 to 40 and the walls 15 to 18 are caused to contact with each other and may be secured to each other by the use of a suitable adhesive or otherwise. Also in folding the arts to the position in this man ner the edg or end portions of the walls may be appreciably outturned as indicated at 40" in Fig. 4 to provide a partial pocket for the inturned panels or plaits. The parts of the container are then folded along the score lines defining the walls thereof and the container set up by securihg the flap or extension 27 to the wall 18 as hereinbefore de-- scribed, and the end flaps or panels folded to position within the closure formed by the walls to provide sunken top and bottomclosures for the container. In this structure, whether or not there is a bead at the top and bottom of the container by forcing the edge portions outwardly as indicated at 40, the inturned panels or plaits and the walls of the container cooperate with the closing panels or flaps in such a manner as to make the end of the container substantially siftproof, it being understood that the end flaps or panels may be connected by .a suitable adhesive or otherwise as is common in the By reference to-Fig. 1 it will be observed to place,

that the cut lines dividing the flaps 19 to 22 extend to the score line 30 so that in folding the end closure parts of 'the container to a continuous strap that is placed ID POSltlOH before any of the other parts of the container are folded to place which is the preferable formation in other instances.

In setting up the container, as illustrated in Figs. ,1 to 5 of the drawing, reference may be made to Figs. 14 to 17 inclusive. In' this operation the oppositely disposed flaps are preferably inturned in sets or pairs,

although, as Will be understood, it is not necessary to turnthe flaps inward in any particular manner. As illustrated,however, and referring to one end of the container, the flaps 21 and 19 are inturned so that the opposite edges thereof contact with and preferably wedge against the adjacent surfaces of the walls 16 and 18 immediately below the inner edges of the panel members 34 and 36. The other or oppositely disposed set of flaps, namely the flaps 22 and20 are then inturned so that the opposite edges for example of the flap 20 icontact with the outer faces of the panel members 33 and 35, and similarly the opposite edges of the flap 22 bear against and may be wedged with these outer facesof the panels 33 and 35. Furthermore, dependingupon which flap is last turned the end of the same is made to contact with and preferably wedge against the outer face of the opposite panel member. For example, if the flap 20 1s nturned last it will wedge at its free end agalnst the outer surface of the panel 36, whereas if the flap 22 is turned in last its outer edge will bear against and preferably wedge with the outer surface of the panel member 34.

, The form of the invention shown 1n Flgs. 6, 7 and 8 is somewhat similar to that shown in-Figs. 1 to 5 inclusive. In this form of the invention the walls of the con- I tainer are indicated at '41, 42, 43 and 44.

and 52, and-those of the wall 44 at 49 and 53. In this form of the invention, however, instead of employing the inturned panels or plaits as shown in Figs. 1 to 5 inclusive the walls of the container along.

lines dividing the same from their respective end flaps or plaits are provided with a rib and corresponding groove as indicated at Y container.

'across the container.

54 and 55, the rib 54 being in the line between the walls of the container and their end flaps or panels-46 to 49 and the rib 55 between the walls of the container and their end flaps or panels 50 to 53. In this form of the invention the parts, after having the walls set up by connecting the flap 45 to the .wall 44, are turned to the positions in which the end flaps or panels are indicated in In this position, as will now be understood, a portion of the surface of the grooves at the inner sides of the ribs 54 and 55 bears against and may be secured to the adjacent surfaces of the inner surfaces of the walls and may be secured thereto by adhesive or other similar material in the same manner and to perform the same functions in substantially the same way as the inturned panels or plaits shown and described in the form of the invention shown in Figs.

1 to 5 inclusive. By reference to Fig. 8, it will be seen that in this form of the invention, when the container is completed, there is a sunken top and bottom and a rib or bead 56 defining the same at the ends of the It will be understood, however, that while I have herein shown and described containers in which the blanks are so shaped that both the tops and the bottoms will be sunken and reinforced, the blank may be so shaped that merely the bottom of the container will be thus constructed, while the top thereof may be made and closed in the ordinary or any suitable manner.

In carrying out the invention, the end or ends of thecontainer may also be so constructed as to be interfolded and interlocked to make a transverse bridge or reinforcing member extending dlagonally Such' a structure is shown in Figs. 9 to 13 inclusive. By reference to the blank from which this form of container.

the container is constructed and as shown in Fig. 9, it will be seen that provision is made for the walls as indicated at 57, 58, 59 and 60 and the wall 57 is provided with the usual flap or extension 61 to be suitably connected to the wall 60 in setting up the The blank as indicated in Fig. 9' provides for a top and bottom of the container 'to' be similarly constructed and as these parts are alike, but one of them Will beparticularly described. As illustrated in this figure the end flap for the wall 57 is composed of the panels 62 and 63, the end flap of the wall 58 by the panels 64 and 65, the end flap for the wall 59 by the panels- 66 and 67, and the end flap for the wall 60 by the panels 68 and 69. ,The panels 65 and 66 are separated along a out line 70, while the panels 63 and 64 and 67 and 68 are divided by score lines 71 and 72 respectivelygazvhich lines are continuations of the score-line'sdefining the walls 57 and 58 and th walls 59 and- 60. The end flap comprising the panels 62 and 63 is provided with a diagonal score line 73 defining these panels 62 and 63. Similarly a 'diagonal score line 74 defines the panels64 and 65' of the end flap of the wall 58; a diagonal score line 75 defines the panels 66 and 67 of the end flap' of the wall 59, and a diagonal score line 76 defines the panels 68 and 69 of the wall 60. A score line 77 and a score line 79 define the adjacent edges of the walls of the container and their respective end flaps, and intermediate of the score lines 77 and 79 there is a parallel scoreline 78. These score lines 77. 78 and, 79 define panels or plaits 80 and 81 and between the wall 57 and its end flap; panels 82 and 83 between the end wall 58 and its end flap; panels 84 and 85 between the end wall 59 and its end flap; and panels 86 and 87 between the wall 60 and its end flap.

In the formation of the container from the blank illustrated in Fig. 9 and as hereinbefore-described, the panels 81 and 83 are folded on the score line 79 to contact with the inner surfaces of the walls 57 and 58. The panels 80 and 82 are then folded in the opposite direction so as to contact with the adjacent surfaces of the panels 81 and 83., Similarly the panels 85 and 87 are folded to contact with the walls 59 and 60 and the panels 84 and 86 with the adjacent sur-- faces of the panels 85 and 87. In this construction the panels when thus folded to position form a complete continuous double reinforcement at the end closure portions of the container. The walls of the container are then set up by suitably securing the flap 61 to the wall 60 and the parts inthis position will then assume the form shown in Fig. 10 in which there is a double inturned plait or panel for each wall of the container. The extending end flaps of the walls 59 and 60, for example, may then be folded along the score line 72 causing the panels167 and 68 to approach one another and to finally have their adjacent faces in contact with each other, in whichposition the panels 66 and 69 comprise one layer or portion of the end of the container as indicated in Fig. 13. Then, and in a similar manner, the

\ outstanding end flaps of the walls 57 and 58 may be folded 'along the score line 71 causing the panels 63 and '64 to approach one another and to enter between the panels 67 and 68. The folding of the end flaps of the walls 57 and 58'is continued in this manner until the adjacent faces of the pan- 1 els 63 and 64 contact with each other when the panels "62 and 65 form the outer mend bers of the end of the container, as clearly indicated in Fig. 11. This, as will he understood, forms a structure in which the panels 67 and 68 are interlocked with the panels 63 and 64, and these parts may be.

suitably connected by adhesive or otherwise extend diagonally across the container as clearly indicated in Fig. 12 to form a bridge or reinforcing member. In this particular formation the end of the container is not sunken. It will be readily understood, however, that the panels 80, 82, Si and 86 may be dispensed with so as to dispense with the double formation of the inturned panels or plaits and the end flaps constructed insubstantially the same manner and folded to position in substantially the same way to form the container in which the end is sunken in the same manner as that described in the other forms of the invention.

In all "the forms of the invention hcreinbefore described, as well as in other equivalent forms thereof, the inturned or set in panels provided at the closure ends of the container form a reinforcing member and if necessary I may also employ an insert strip composed of suitable fabric or wire or other material to lend the necessary strength to this reinforcing strip in instances where the same is required. Furthermore the inturned or set in reinforcing panels may be single, double or multiple in the application as may also be necessary. For example, as shown in Fig. 18, a strip or band 87 of suitable fabric or other material may be placed between the inturned panels and the adjacent wall member and secured thereto by a suitable adhesive or otherwise. This band may be made of fabric or any'other substance adapted to serve the purpose of reinforcing the panels formed at the ends of the container.

In the formation of the containers in the class to which my invention relates as ordinarily constructed it is necessary in forming the container to set the same upon a block or equivalent member in order to square or shape the' parts thereof, at the same time turning the end flaps to position and so securing them by the adhesive or other similar substance employed. The container constructed in accordance with my invention makes it possible to dispense with the use of this shaping block in the formation of the container, it being apparent that by the insertion of the closure ends. or flaps within the walls of the container that the same will the flaps being adapted to be turned in whereby the opposite edges of each flap coact with the inner faces of adjacent walls or the outer faces of adjacent panels to form an inset siftless closure in the container.
